Xterm users may want to add something like the following to their
.bashrc. It sets the working directory and hostname in the title bar,
and writes the prompt with underlining.
Also, the function 'setname' changes the icon name, and the
prefix of the title bar.
Note that what may look like ^[ and ^G are <Escape> and <Bell>.
Brian, you are welcome to include this (or something similar)
in the examples directory.
